BELZONA CONTRIBUTES TO PUMP EFFICIENCY PROGRAMME IN STEEL PLANT
Industry: General Industry (GIND)
Application: CEP-Centrifugal Pumps (CEP)
Substrate: Steel
Customer Location: Steel plant, Hungary
Application Date: 2010
Products:
Belzona 1111 (Super Metal)
Belzona 1341 (Supermetalglide)
Problem: Damage due to erosion and corrosion caused high efficiency loss. The 12 selected pumps are 15 years old. But there are another 60 pumps 30-36 years old which have certainly higher efficiency loss as the tested ones.

Application Situation
Continuous casting plant of a steelmill has over 60 pumps used to provide cooling water to casting rolls, burner injectors of blast furnace and other different areas. 12 pumps were identified for coating and efficiency monitoring.
Application Method
Application was carried out in accordance with Belzona Know-How System Leaflet CEP-10.
Belzona Facts
Steelmill installed new digital control system for the proper monitoring of power consumption, volume and water pressure. Before and after result: -10-12% less power consumption +12,5% more pressure +12,5% higher head. The energy saving in a year covers the cost of the coating.
